Essay - 4
We know 21st centenary is centenary of technologies. So nowadays we are getting information second by second and being connected to anyone anywhere. Therefore people should know about computer networks.
May you think what is the basic knowledge of computer networks. Basic knowledge are divided into following categorized:
In the beginning we want to talk about setting up simple network. It should be easy to understand. There are should be a router, computers and ethernet cable. A router has bunch if ports in the back. Firstly router is connected to computers with cables and give ip address the computers. Second thing you do with a router is to connect it to the internet. Do it by hooking up an ethernet cable to the are
port in the back that looks different from all the other ports. That's it.
There are several different types of network device:
They are Bridge, Hub, Switch, and Router.
Bridge : Bridge is a connectivity device that forwards data based on physical address.
Hub: A hub is connectivity device to which network cables are attached to from network segment.
Switch: A switch is aware of address assacioted with each of its ports and forwards each incoming data frame to the correct port.
Router: A router is connectivity device that filter and forwards data based on a logical address.
There are several difference types of computer network.
That can be characterized by their size as well as their purpose.
The network topology is virtual shape or structure of network.
Types of network topologies are:
May you think what is the basic knowledge of computer networks. Basic knowledge are divided into following categorized:
- How to setup network,
- Network devices,
- Types of network,
- Topology
- Troubleshooting.
Let's see about more details.

There are several difference types of computer network.
That can be characterized by their size as well as their purpose.
- PAN is a computer network organized around an individual person.
- LAN is individual offices network.
- MAN is larger then LAN
- WAN can contain multiple smaller networks, such as LANs or MANs.
The network topology is virtual shape or structure of network.
Types of network topologies are:
- Bus topology use a backbone technology .
Backbone is single core cable and use a large bandwith - Ring topology common used to a campus network.
Every device has two neighbors. - Star topology is used to a home network. There has central connection point wish as Hub, Switch or Rotuer.
- A Tree topology joins multiple star topologies.
- Mesh topology introduces the concept of routers.
People call IT professionals about network connection problems. But man problems are easy to fix without help. Investigate IP address issues. This group of numbers allows communication on the internet. Renewing your DHCP fixes most IP problems. The router links LANs to the internet. Make sur the router's configuration is correct wireless signals.
Finally you should be familar with some basic networking terminology and be able to understand how different components are able to communicate with each other. This should assist you in understanding about different categories of networking.
